.To ad whom it may concern.:

Be it known that I, DAVID S. KENNEDY, of the borough of Brooklyn, county of Kings, and State of New York, have invenfted a new 5 and useful Improvement in Linotype-Machines, of which the following is a specification.- v

Thisinvention has reference to the knives which are lemployed for trimming the side xo faces of linotypes -or printing slugs after .their delivery trom the mold in which they are cast.

In the form shown it is intended more particularly for use in Mergenthaler linotype x5 machines` of the general organization represented in Letters lvatent of the United States #436,582. AIn vthese machines, an ejector l drives the slug or linotype out of the mold and between two parallel knives in therezo ceiving galley, one of the knives being adjustable in relation to the other in order to -dress yor trim the slugs to the various standard thicknesses, as nonpareil, brevier, etc.

My improvement has in view a very -speedy and accurate adjustment of the movable knife and the supporting of the same yfirmly against the strain and pressure to whichit is subjected during the passage of the slugs'. l 3o- To this end it consists essentially incombining with the movable knife a movable stepped bar for advancing and supporting the same; in the peculiar construction of the stepped. bar with adjustable steps'or shoulders; and in various other details of' construction.

With the exception of the parts hereinbefore described, the machine may be in all respects of'ordinary construction.

4o In thedrawings-Figurel is a perspec-y tive view from the front of myimproved trimmingvdevice applied to a Mergenthaler machine. Fi 2 is a horizontal vsection on the line 2-2,gFigs. 1 and 3. Fig. 3 is avertical ysection on the line 3 3, Figs. 1 and -2.l Fi 4 is a side view oil the adjusting lever and its ockng devices. Fig. 5 is .a section .on the line 2-2, Fig: 3, through one of the adjustable steps or shoulders. Fig. j'iis a cross- .section on the line. 6*-6, Figs. 2 and 3.. Fig.

7 is a side'elevation of the stepped bar orv slide formed in a single piece. i Referring l. to .the drawings, A represents the rigid 'main-frame of the machine, and A a metal block commonly known as the knife- 5 5 /block, bolted. rigidly to the main-frame and serving to support the trimming-knives and their adjuncts. B and C represent the two upright parallel knives between Whichsljl s areejected and by which the opposite Vs1( e to faces of the slugs are trimmed.

.The knife B is secured rigidly to the main' frame by bolts b, or other suitable means. The opposing knife C is secured by bolts c rigidly to a horizontal slide D su ported and guided, in the knife-block A', so tiiat by moving the slide, the distance between the two knives may be varied. AThe slide D 'carries also two horizontal screws c", which are seated against the back of the knifeC, as a means 7o of adjusting the same on the slide so that it will be exactly parallel with the opposing knife, .and also to prevent the knife from moving back out of position on the slide.

To ermit the adjustment of the knieC on 7 5f the s 1de D the holesin Ethe knife throu l1 which the screws c pass are elongated slight y in a horizontal direction as indicated by the dotted lines in Fig. 2.' L

block and vacting between a shoulder thereon and a shoulder on the slide D, its tendency being to urge the slide outwardand thereby increase the distance between the knives. For the purpose of advancing the slide D 85 against reslstance of the spring and thus decreasing the distance between the knives, I Erovide a vertical slide F guided in the knifelock and provided with a series of steps or toward the shde D, so that as the slide F is moved downward, these shoulders e will act one after another against a stud or rejection d on the slide D and thus move the atter for- .Ward step by step. 9 5 The slide F may be made as in Fig. 7, in

one piece with the ste s or shoulders integral therewith. Inasmuc ,however, as it is difiivcult to produce the solid stepped slide, which must be hardened-'and ground, lwith the roo necessary accuracy, I prefer to make the' steps, as shown in Figs. 2, 3 and 5, inthe form of threaded studs or screws. Thusormed,

they may be turned forward through and j beyond the slide the exact distancesrequired' p05 and then. Ilocked permanently in place by means of tubular set-screws e', or equivalent ,I screws, seated tightly .against them.,

E represents a spring seated in the knife- A8oshoulders e projecting differentdistances ce The screws or studs may be cheaply con structed by automatic machinery, and being small, they may bel tempered to an extreme degree of hardness.`v They' may be adjusted in approximately the required positions, vand j thereafter ground away at the operative ends to the exact height required, or they may be adjusted to their final position in the first in stance. l

In the event of either one of the steps l wearing away, it need only be set forward to l position.

sive standard thicknesses.. In som.e.cases, however, 1t 1s desirabletoproduce slugs of intermediate or bastard thicknesses. In this connection the adju stable steps or shoulders are of especial advantage, since any one of them may be adjusted, independently of,

the others, to set the knife in any required The steps on against the slide D, but I prefer 'oo-provide the latter, as shown, with the bearing stud or projectiond before referred to, and'this-.for

' the reason that the stud separately constructed may be made very hard, the better toresist wear, and to be replaced, if worn, by another.

'lhe slide F may be actuated by any suitable means, but I prefer to employ, as shown, a hand-lever H pivoted to the knife-block at h, and having its rear end provided with a slot 7L to receive a stud shown in Figs. 1 and 2, so that the movement of the lever may serve to raise and lower the slide F and thus effect instantaneous adjustment of the knife C. A

The knife is inove'd positively toward its companion by the slide F and is supported thereby firmly in the required .position. When the slide is raised, the knife will be permitted to receive from itscompanion step by step under the infiuenc'e of spring E.

The parts may be fitted with sufficient friction to remain in their adjusted positions, but I prefer to provide the lever H with a locking device. latch or lever 71.2, pivoted to the side ofrlever H, and provided with two locking-pins h, h4,

the 'slide F may act directlyf on the slide F, as

In the form shown, this consists of a arranged to alternately enter holes v in aV sector-plate or flange formed on the kniferblock. The spring h acts on the latch li2 and tends to press the opposite end of the latter and the pins therein toward the locking holes, so that the pins will enter automatically and lock the lever and knives in their various positions. A

It will be observed that the holes r" are arranged in two rows and alternate as shown in Fig. 4. rlhe holes in one row receive the pin ha, while those in the other row receive the pin h4. This arrangement is adopted for the reason that it permits in a limited space the use of large pins and large holes.

Of course it will be understood that any other suitable means may be used for locking the lever in its various positions.

and desire to secure by Letters Patent:-

1. In a linotype machine, the combination of a movable knife,a spring tending to move the saine in` one direction, Aand a step ed slide to move the same in the opposite irection, the steps of said slide being independently adjustable in height. l y

- 2. In a linotype machine, the combination ofa knife-block, a slide mounted therein, the knife secured rigidly to said slide, a spring tending to move the slide in one direction, a second slide having stepsor shoulders to advance and support the first-named slide, a lever arranged to move the second slide, and means for locking said lever in predetermined positions.

of a knife-supporting slide, and an actuating member having independently adjustable steps or shoulders; whereby the knives may be set to dress slugs to standard or bastard thicknesses, as demanded.

4. In combination, a support A', a slide D sustained thereby, a' slide F provided with adjustable steps e, a lever for moving said slide, and a spring'acting on slide D in opposition to slide F.

5. In a linotype machine, a lmife-ndjusting member consisting of a body-portion F, screws or studs c, and locking screws e.

In testimony whereof I hereunto set 'my hand this twenty third day of February. 1907, in the presence of two attcsting wit- Witnesses:
